So there are no modern alternatives, and most of the designers who used them are retired or dead. Jan 17 at I’m not familiar with driving Nixie tubes, having never worked with them, but the circuit diagram given in the ‘s datasheet has a reverse-bias zener diode to ground for each pin, although I’m not quite sure I understand the purpose of it. Hex 2-input NOR enable buffer.
The ‘s datasheet includes an equivalent circuit diagram for its output stage. Just have a look at what all the modern nixie tube equipment uses.

Dual 4-input NOR gate. Octal 3-state bus tranceiver. What is a modern SN alternative? Are those packages the Russian DIP with 2. I had been sourcing various components for my projects some time ago, and they were of year 89, as well as of Anonymous 5, 1 7 If this question can be reworded to fit the rules in the help centerplease edit the question.
You could always just replicate that output stage in discrete components and use a modern decoder IC e. Nixies have not been designed into new equipment in perhaps 40 or 50 years. BCD to decimal decoder. Quad 2-input NOR gate.
